Greetings from Ireland!

I have purchased a 2012 730 LD F02, where the rear entertainment system is operated by a remotecontrol (as opposed to an idrive). The remotecontrol is missing (the dealer said the previous owner's kids had lost it). I know I can purchase an original one from BMW, but they're very expensive, for something that won't get a lot of use.

It is worth the risk of buying a second hand one online, and are they difficult to program to a different car?

Also, there's a DVD stuck in the player. Pressing the Eject button causes it to click and whirr for a while, and then it stops. Is there a way of getting the DVD out, without having to take the unit out?
